Big, strong, controlling lineman that constantly pushed blockers off the ball and into the backfield. Was dominant at times and could not be stopped. Did not show great quickness or a closing burst. More of a gap occupier and pocket collapser than playmaker.

Campbell was one of the country's top defensive tackle recruits coming out of Detroit Cass Tech in 2009, but the five-star prospect arrived on campus overweight -- tipping the scales at about 356 pounds -- and fizzled early in his career.

He was moved to the offensive line during the 2010 season, but switched back to defense the following offseason. He was a reserve in 2011 before finally breaking out as a starter in 2012.

Campbell finished with 44 tackles, which led Michigan's defensive linemen and helped him land on NFL radars. ESPN draft guru Mel Kiper Jr. said Campbell is a candidate to be selected in the late rounds of April's draft.

CBSSports.com ranks him the No. 18 defensive tackle prospect and projects him as a sixth-round draft choice.

After spending three years tagged as a five-star bust, Campbell's NFL dream appears to be alive and well.
